4. Maintenance
The control unit should be inspected once per
year. At each inspection:
Check the control unit for obvious signs of
damage to the case or its lid.
Check the condition of the control unit
standby battery.
Check the cabling to the keypad(s) and
expander(s) for signs of damage or wear.
Check the keypads for obvious signs of
damage.
Test the action of all buttons on all keypads.
Clean the keypad surface and display. To
clean the keypad wipe the surface with a
clean soft dry cloth. Do not use water,
solvents or any proprietary cleaning materials.
Monitor the signal strength and battery
condition of all detectors, radio keypads,
remote controls, HUAs and radio sounders.
Test each device. Replace batteries as
recommended by the manufacturer’s
instructions.
Gently clean the lenses of any PIRs with a
clean, soft dry cloth. Do not use water,
solvents or any proprietary cleaning materials.
Walk test all detectors.
Test any external sounders and strobes.
Note that if you wish to find the location of any
keypad or expander you can employ the
Test –
Locate Bus Device
option in the Installer Menu. Use
this option to make a selected bus device give a
continuous tone from its sounder. Once you have
found the bus device you can silence the tone
either by opening the case and so activating the
device’s tamper, or by pressing
on the keypad
from which you are carrying out the test.
Replacing or Removing Wired Keypads
If you need to remove or replace a wired keypad
from the system at any point then you must follow
the correct procedure.
Before
physically
disconnecting the keypad enter the Installer
Menu. Then:
To permanently remove a keypad:
Use the
Devices/Detectors-Wired Keypads-Delete
Keypad
option. This ensures that the system does
not report a missing keypad and the keypad’s
internal address is erased (allowing it to be used
on another system).
To replace a keypad:
Use the
Devices/Detectors-Wired Keypads-Replace
Keypad
option. This ensures that the replacement
keypad will retain the programming of the old
keypad.
See the
i-on Engineering Guide
for more details.
Note: If you are replacing a keypad on a single-
keypad system then you will have to re-program
the new keypad with all the functions of the old
keypad, including any non-default ABCD key
functions.
